Description
Summary:Abstract. Oceanic uptake of anthropogenic CO2 results in a reduction in pH termed “Ocean Acidification ” (OA). Com-paratively little attention has been given to the effect of OA on the early life history stages of marine animals. Conse-quently, we investigated the effect of culture in CO2-acidified sea water (approx. 1200 ppm, i.e. average values predicted using IPCC 2007 A1F1 emissions scenarios for year 2100) on early larval stages of an economically important crus-tacean, the European lobster Homarus gammarus. Culture in CO2-acidified sea water did not significantly affect carapace length of H. gammarus. However, there was a reduction in carapace mass during the final stage of larval development in CO2-acidified sea water. This co-occurred with a reduction in exoskeletal mineral (calcium and magnesium) content of the carapace. As the control and high CO2 treatments were
